Title: Systems and methods to securely generate shared keys
Inventor: BROWN MICHAEL S
IPC: H04L9/14
Filed: 2005-05-02
Abstract: A method for secure bidirectional communication between two systems is described. A first key pair and a second key pair are generated, the latter including a second public key that is generated based upon a shared secret.  First and second public keys are sent to a second system, and third and fourth public keys are received from the second system. The fourth public key is generated based upon the shared secret. A master key for encrypting messages is calculated based upon a first private key, a second private key, the third public key and the fourth public key. For re-keying, a new second key pair having a new second public key and a new second private key is generated, and a new fourth public key is received. A new master key is calculated using elliptic curve calculations using the new second private key and the new fourth public key.

IPC: C09K8/62
Filed: 2006-10-25
Abstract: Hydrocarbon stimulation fluids are often used to increase the permeability and productivity of oil and gas reservoirs. The fluid itself is made up of a mixture of hydrocarbons and various chemicals designed to induce gel formation and gel breaking. The successful removal of these chemicals from the fluid has been achieved, through a process of acid-washing, mixing with a settling agent, centrifugation and filtration. This will allow the fluid to be re-used many times for further fracturing processes.

Patent CA-2568112-A1 (CA)
Inventor: KONECSNI PATRICIA
IPC: B44D3/12
Filed: 2006-11-20
Abstract: "This plastic paint can lid with a transparent zone is specifically designed to add value and render it attractive as a replacement to existing metal lids in production, or as an aftermarket or impulse purchase. This has come about through the recognition that current metal paint can lids are deficient in several ways. For example, they are opaque and it is not possible to see either the volume of paint or its colour.  Replacement of lids, onto tins after use, is an experience most people dread both for reasons of their tight fit and the resultant force required to properly and completely seal the tin, and because of the risk of paint spattering if the lid is hammered on without a drop sheet or rag in position to catch paint left in the groove of the tin. Traditional lids also possess a slippery surface which requires careful placement and alignment of other cans stacked on top, if tumbling stock is to be avoided. Furthermore, paint will not adhere to plastic lids and these lids can be stored for future reference and use."

Abstract: A handheld electronic device with a reduced QWERTY keyboard and disambiguation software. The device outputs a default output and a number of variants. The output is based largely upon the likelihood that a user intended a particular output, but various features of the device provide additional variants provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Abstract: A method of operating an aluminium electrowinning cell that has one or more metal-based anodes (5) . The anodes (5) comprise metal-based foraminate anode bodies (10) which are suspended by metal-based anode stems (20) in a molten electrolyte (50) and which are spaced above a cathode (30). The method comprises electrolysing alumina dissolved in the molten electrolyte (50) by passing current via the anode stems (20) and the anode bodies (10) through the electrolyte (50) to the facing cathode (30) whereby aluminium (60) is cathodically produced and gas is anodically evolved. The gas promotes an electrolyte circulation (51) through the foraminate anode bodies (10) which facilitates dissolution of alumina. Each anode (5) has a foraminate anode body (10) suspended by least three anode stems (20) that are spaced apart from one another and distributed around a foraminate stemless central part of the anode body (10). These stems extend from the anode body (10) to above the molten electrolyte (50), the electrolyte (50) flowing up through and above said foraminate central part of the anode body (10) to enhance dissolution of alumina fed thereabove.

Abstract: Demineralized bone matric (DBM) and native bone morphogenetic protein (nBMP) are complex mixtures of non-collagenous bone proteins. These mixtures contain many of the BMPs that are available as recombinant molecules. Information regarding the presence in these materials of molecules that may affect the availability and activity of the BMPs is very limited. A chemical extraction of DBM, such as using alkali-urea produces a water soluble extractate which inhibits the osteogenic activity of DBM. Noggin, an extracellular BMP ligand antagonist is found in the water soluble extractate from DBM. Differential chemical extraction is a useful means of removing non-osteogenic, or osteogenic inhibitory molecules from DBM and nBMP.

Title: Efficient coding and decoding of transform blocks
Inventor: SRINIVASAN SRIDHAR
IPC: H04N7/12
Filed: 2006-08-03
Abstract: A block transform-based digital media codec more efficiently encodes transform coefficients by jointly-coding non-zero coefficients along with succeeding runs of zero-value coefficients (Fig. 14). When a non-zero coefficient is the last in its block, a last indicator is substituted for the run value in the symbol for that coefficient (Fig. 14, item 1435). Initial non-zero coefficients are indicated in a special symbol which jointly-codes the non-zero coefficient along with initial and subsequen runs of zeroes (Fig. 14, item 1440). The codec allows for multiple coding contexts by recognizing breaks in runs of non¬ zero coefficients and coding non-zero coefficients on either side of such a break separately (Fig. 14, item 1460). The codec also reduces code table size by indicating in each symbol whether a non-zero coefficient has absolute value greate than 1 and whether runs of zeros have positive value (Fig. 14, item 1475), and separately encodes the level of the coefficients and the length of the runs outside of the symbols (Fig. 14, item 1490).
